To on whom it may concern.-

Be it known that I, CHESTER T. DRAKE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Oonveyer Attachments forMixing-Machines or the Like and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to an improved conveyer attachment designed to beemployed in connection with a concrete or analogous machine of that typein which a mixer-vehicle is adapted to be conveyed from place to placeand the material discharged from the mixing-chamber is carried by theconveyer directly to the point where it is desired that the material bedeposited for immediate use.

It is desirable in conveyers of the type mentioned that they be capableof swinging laterally to a greater or less extent andthat the drivinginstrumentalities for the conveyer be so arranged 1 that the leastpossible mechanism be necessary. To attain this object, the inventionherein contemplates the employment of a turn-table, upon which issupported said operating means in a manner that no matter what be theposition of the conveyer laterally relative to the machine power will bedirectly applied to the conveyer, so that the provision of complicatedoperating mechanism to permit this lateral movement of the conveyershould the same be mounted upon the vehicle itself is entirely obviated.

The invention also embraces the idea of supporting at the inner end ofthe conveyer a hopper of suitable type adapted to receive the materialdischarged from the mixer and direct the same onto the conveyer.

The invention also relates to improved means for supporting andvertically adj usting the outer or free end of the conveyer.

Novel details in the construction and arrangement of the several partsof the con' veyer will beapparent from the detailed descriptionhereinafter and the appended claims when taken in connection with theaccompanying drawings, forming part hereof,wherein apreferableembodimeut of the invention is illustrated. In said drawingslike reference characters designate corresponding views.

Figure 1 is a side elevation of the improved conveyer shown assupportedat one end of the mixer-vehicle, parts being broken away. Fig.2 is a plan view of the conveyer andits operating means, and Fig. 3 is adetailed sectional view on the line m 00 of Fig. 2.

Referring more specifically to the drawings, A designates the end of aconveyer designed to convey a mixer B of any desired type, the vehiclebeing provided with suitable wheels or runners to travel upon theordinary plain surfaces or with'flanged track- Wheels, if foundexpedient. At the extreme forward portion the vehicle is provided on itsupper surface with a substantially semicircular metallic bearing-plateC, and disposed to ride upon said bearing-plate is a turn-table D,pivotally secured thereto through the medium of the pivot-bolt d. Atopposite points on the turn-table and rigidly secured thereto arebrackets E, parallel at their outer ends and extending in a directionlongitudinally of the mixer.

F. F are side strips, preferably of angleiron, carrying at their outerends a pulley or roller G, over which a suitable conveyer-belt H ofdesirable form is adapted to pass, the same at its opposite end passingaround a similar pulley or roller G, pivoted in the brackets E. Thisconveyer-belt is supported intermediate its ends upon relatively smallerguide-rollers g g, supported in perforated ears extending, respectively,above and beneath the side supporting-bars, and that a desired tensionmay at all times be exerted upon the belt the ends of the side bars areslotted, as at '11, in which is adjustably mounted the ends of the axleof the roller G, the same being supported in suitable boxes and theadjustment being eifected through the medium of the screw-threaded stemt", passing through the end plates i and engaged by the nuts i That theconveyer-belt may be elevated and lowered when desired the inner ends ofthe side bars are pivotally secured at J to the parts in the severalouter ends of the brackets E, the connection being through the m ediumof projecting stubs j, rigidly secured to the sides F and adapted torotate in the journalsj', rigidly secured to the brackets E. Thisconstruction is best shown in Fig. 3. At approximately the outer end ofthe conveyer in suitable uprights k a pulley 7c is supported, aroundwhich works an operating rope or cable K, the same being secured at oneend over a hook k upon the standard L on the vehicle and the free endprojecting outwardly over a pulley k at the upper endof said standardand'thence downwardly around an operating-drum K. The rope is guidedbetween parallel verticallydisposed rollers L, which insures the sameagainst working out of the grooved periphery of the pulley when theconveyer is swung from side to side. By this arrangement a simple butefficient mechanism is provided for suspending the outer end of theconveyer at different elevationswhile in operation and for elevating thesame alongside the vehicle when not in use. At the center of the turn:table in alinement with the conveyer-belt is mounteda motor M of anyconvenient type, that shown being preferably a steam-engine adapted toreceive its source ofpower through a flexible pipe connection m, leadingto, a steam-supply. This motor has the usual pitnan m, connected at itsends with a crank m mounted upon an axle m the axle in turn beingrotatably supported in standards m At one end of the axle a relativelysmall gearwheel N is secured, transmitting motion to the shaft 0 throughthe relatively larger gear N (broken away in Fig. 1 to show the bracketE) at the end of the shaft and the connecting-chain 17.. At the end ofthe shaft opposite the gear N is a relatively smaller gear P inoperative connection with a relatively larger gear P through the mediumof the chain 1). The lastmentioned gear is attached to the projectingend of the axle of the belt-roller G.

A hopper R is supported upon the brackets E above the inner end of theconveyerbelt and beneath the end of the mixer. The

hopper may be supported in any suitable manner-as, for instance, bymetallic straps R. The hopper is preferably funnel-shaped, terminatingina reduced outlet 1', so that the ingredients which have been mixed willnot either vertical or lateral, the operating mechanism will at alltimes have direct connection by reason of the side supporting-bars beingpivoted as shown and the driving-motor being carried by the turn-table,the desired traveling motion being imparted to the conveyer-belt throughthe medium of the gearing hereinbefore described.

The forward edges of the turn-table and its bearing-plate may be beveledor the table may have secured toits upper surface a suitableguide-roller to facilitate the travel of the chain a thereover.

. \Vhile a special construction has been delineated in the drawings, itis to be understood that such constr-uction is shown for the mere sakeof assistance in understanding the in'ventionand that various changesand alterations in the arrangement and details may be made Without inthe least departing from the nature and spirit of the invention.
